<p>The drum (5) has a drum body (7) mounted at a frame (9) for rolling a rope. A crank (12) is connected with the drum body in a torque-proof manner for rotation of the drum body around a longitudinal axis (6). A safety device is provided as an anti-twist plate of the drum body relative to the frame. The safety device is implemented in such a manner that the crank is shiftable between a locking position and an unlocking position by a radial pulling of a crank arm (14) of the crank relative to the longitudinal axis. The safety device has a lock arm firmly connected with the crank arm.</p> |
